CLIPPER' Filed April 2, 1929 Patented Mar. 1, 1932 UTED ,STATES` ALBIN RITZMANN, or'rsrnLD, GiirtrrlnvYy oLrPPER Application filed April 2, 1929, Serial No. 351,989, and in Germany February 14, 1928.

My invention relates to improvements iny clippers, and more particularly in clippers of the type comprising ixed and movable cutter plates, and the object of the improve- '5 ments is to provide clippers in which the movable cutter plate is adapted t be operated by both handles, the said handles being rockingly mounted 0n the frame carrying the cutters and being positively connected with each other. Thereby the critters are capable of rocking movement relatively to the stationary cutter frame, so that the said frame is capable of maintaining its position relatively to the hair even when inclining the hand, and pain to the customer by accidental movement of the hand is avoided.

For the purpose of explaining the invention two examples embodying the same have been shown in the accompanying drawingsin which the same reference characters have been used in all the views to indicate corresponding parts. In said drawings,

Fig. 1 is an elevation showing the clippers with the xed cutter plate removed,

Fig. 2 is an elevation showing the fixed cutter plate,

Fig. 3 is a sectional elevation taken on the line 3 3 of Fig. 1, n

Figs. 4 to 6 are detail views forming parts of a modification ofthe clippers, and

Fig. 7 is a sectional elevation showing the clippers illustrated in Figs. 4 to Gassembled.

In the example shown in Figs. 1 to 3 the clippers comprise a stationary cutter plate 1 and a cutter plate 2 which is transversely movable relatively to the stationary cutter plate 1, both cutter plates being in the form of combs, as is known in the art. The handles 3 and 6 are rockingly mounted respectively on pivot bolts 4 and 7 rising from the frame 5 of the clippers, and they are'acted upon by a spring 8 placed on the said pivot bolts and engaging with their free ends 9 and 10 the inner sides of the handles 3 and 6 thus tending to spread the said handles apart. The hubs of the handles are positively connected with each other, the hub of the handle 3 being formed with a tooth 11 engaging in a corresponding notch of the hub of the handle 6, the said tooth and notch insuring rockone cutter plate being engaged by one of the r ving movement of both handles in opposite directions.

.One of thehandles is provided with an e;;tension formed with a nose 12 engaging in a-notch of the movable cutter plate, so that B6 when operating the handles 3 and 6 relatively to each other the cutter plate 2 is moved 'transversely of the cutter plate 1.

Both cutter plates are held together by means of a screw bolt 14 and a nut'l5, the 00 said nut bearing on an elastic washer 16.

In the modification shown in Figs. 4 to 7 the handles 3 and 6 are rockingly mounted on the same pivot bolt 17. Between the handles there is a slidable disk 21 acted upon by a spring 22 tending to push the same laterally and into engagement with the plate 5 `of the trame of the clippers.

Above the said pivot bolt 17 the hub of the handle 6 is provided with a pin 19 engaging 0 in a slot 20 of the disk 21, and below the said pivot bolt the hub of the handle 3 is provided with a pin 23 engaging in a slot 24 of the disk 21. Thus, when rocking the handles 3 and 6v relatively to each other the pins 19 and 23 "75 shift the disk 21 in the same direction. TheV spring 22 tends to spread the handles 3 and 6 apart. The disk 21 is made integral with a lug 25 engaging in a notch of the movable cutter plate, and it carries the said cutter plate along for moving the same in transverse direction. The cutter plates and the frame are held together by a bolt 14', a nut 15 and an elastic washer 16.

Instead of providing a single movable cutter plate adapted to be operated by both han'- e dles two cutter plates movable in opposition to eachother may be mounted on the frame,

handles, and the other cutter plate by the 9 other handle. I claim:

j 1. A hair clipper comprising a lixed cutter plate having teeth at the `front end, a movable cutter plate slidably mounted on the front end and innerside of the fixed plate and having teeth at its front end and also provided in its rear side with a notch, a pair of handles pivotally mounted on the inner rear e Side of the xed plate for simultaneous movement in reverse directions, said handles having interengaging gear elements of the same radius, so that said handles are directly geared together for simultaneous movement at the same rate of speed, one of said handles also having Va lug engaging in the notch of the movable toothed plate and a spring act-ive to move the handles apart.

2. A hair clipper as claimed in claim l, including headed pins ony which the handles are pivotally mounted and in which the spring which moves the handles apart has coils arranged around the heads of said pins andhas end portions connected to the opposing inner sides of the handles.

' In testimony whereof I hereunto affix my signature.
